The correct answer is B) Between 1935 and 1939 war broke out in Europe and Asia.
The statement that explains why the Neutrality Acts changed between 1935 and 1939 was “Between 1935 and 1939 war broke out in Europe and Asia.”
The United States government passed the Neutrality Acts in early 1930 because he wanted to stay neutral and not getting involved in foreign affairs. But that changed in March 1941 with the passing of the Lend-Lease Act that provided military aid to other nations in World War II. With this Act, Congress allowed President Roosevelt to support other Allied countries in war with weapons or military aid.
